Activities this quarter were conducted under Tasks 2, 3, and 5. Task 2 work concentrated on evaluating the effects of low-severity, first-stage reaction conditions on coal conversions of lignite, subbituminous, and bituminous coals. The impact of artificially weathering bituminous coal was investigated. Large quantities of first-stage product were made using the one-liter reactor for subsequent filtration and catalytic upgrading tests. Test conditions and coal conversions for all microautoclave and one-liter tests made this quarter are presented. Filtration tests examined lignite, subbituminous, and bituminous coal products. The effects on resid conversion of second-stage reaction conditions and catalyst recycle were studied. Task 3 work included the successful transfer of first-stage reactor products to a receiver and the design of an interstage filter. Task 5 work included an ongoing review of the technical and patent literature and expansion of the annotated bibliography. Mass and elemental balances were obtained for selected tests
